The Eurovision Song Contest 1971 was the 16th edition of the annual Eurovision Song Contest. It took place in Dublin, Ireland, following the country's victory at the 1970 contest with the song "All Kinds of Everything" by Dana. Organised by the European Broadcasting Union (EBU) and host broadcaster Radio Telefís Éireann (RTÉ), the contest was held at the Gaiety Theatre on 3 April 1971, and was hosted by Irish television presenter Bernadette Ní Ghallchóir.

The Eurovision Song Contest, often known simply as Eurovision, is an international song competition organised annually by the European Broadcasting Union. Each participating country submits an original song to be performed live and transmitted to national broadcasters via the Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine a winner.
